A Temporal Fusion Memory Network-Based Method for State-of-Health Estimation of Lithium-Ion Batteries

Batteries
As energy storage technologies and electric vehicles evolve quickly, it becomes increasingly difficult to precisely gauge the condition (SOH) of lithium-ion batteries (LiBs) during rapid charging scenarios. This paper introduces a novel Time-Fused Memory

Fast head-tail instability with space charge

Physical Review Special Topics. Accelerators and Beams, 1998
The fast head-tail instability with space charge is studied using series expansion techniques, numerical simulations, and a new formulation which allows for precise estimates of growth rates and thresholds.

Trade‐off between energy density and fast‐charge capability of lithium‐ion batteries: A model‐based design study of cells with thick electrodes

Electrochemical Science Advances, 2023
Lithium‐ion batteries exhibit a well‐known trade‐off between energy and power, which is problematic for electric vehicles which require both high energy during discharge (high driving range) and high power during charge (fast‐charge capability).

Real-time measurement of lithium-ion batteries’ state-of-charge based on air-coupled ultrasound

AIP Advances, 2019
In order to overcome the drawbacks of the traditional method of measuring a lithium-ion battery’s state-of-charge by charging and discharging its voltage curve, a method based on air-coupled ultrasound is proposed, which slows aging of the battery ...

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Hybrid DC–DC Converter With Novel Clamp Circuit in Wide Range of High Output Voltage

IEEE Access
In this paper, a hybrid converter with a novel clamp circuit is introduced. This hybrid converter integrates a phase-shifted full-bridge (PSFB) converter with a half-bridge (HB) LLC converter. On the primary side, the lagging leg of the PSFB converter is

Fast Estimation of State of Charge for Lithium-Ion Batteries

Energies, 2014
This paper presents a novel impedance-based approach to efficiently estimate the state of charge (SOC) of a Li-ion battery. By using an AC impedance analyzer, a database is constructed, containing records of AC impedance versus SOC.

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

FEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...
